qPCR is an abbreviation of real-time PCR or quantitative PCR, which is a method to measure the total amount of products after each cycle of polymerase chain reaction (PCR) with fluorescent chemicals in DNA amplification reaction. Quantitative reverse transcription PCR (RT-qPCR) is an experimental method applied to PCR experiments using RNA as the starting material. Yeasen not only develops qPCR and RT-qPCR reagents based on probe methods, but also based on dye methods.
